DITCHING' OR EXCAVATING- MACHINE.

Specification of Letters Patent.

Patented Sept. 30, 1919.

Application filed February 11, 1915. Serial No. 7,539.

To all whom it may concern:

Be it'known that I, LEROY P. CLUTI'ER, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Ditching or Excavating Machines, of which the following is a specification.

I This invention relates to excavating machines chiefly used for excavating cellars, and widening water courses, and has for its object to provide a simply constructed and 1 operated mechanism for loading, elevating and emptying a scoop and which may be attached to any suitable machine available for the character of the work referred to.

- The invention consists mainly in the arrangement of the scoop, the scoop-carrying member, and boom for the two pulling memhers-making it possible for the operator, to extend the scoop beyond theend of the boom,- to raise and lower the boom or fill the scoop by manipulating the two pulling members.

With. the foregoing and other objects in view the invention consists of the novel construction, combination, and arrangement ofparts as hereinafter more specifically described and illustrated in theaccom anying drawings, whe in is shown an em odi-- v ment of the invent on, but it is to be understood that changes, variations and modifications can be resorted to which come within the S00 e of the claims hereunto appended.

In t e drawings wherein like reference characters f denote corresponding parts throughout the several views Figure 1 is an elevation of a ditching or excavating machine showing the adaptation therewith of the elements in accordance with a .this invention.

Referring to the drawings indetail 1 de-" 7 notes a scoop-carrying member having pivotally connected therewith as at 2 a scoop 3. The latter is provided with braces. 4, connected by a pin 5, which is 'movably mounted in a slot 16, between ides 6.and the scoopoarrying member 1. ally connected with scoop 3 as at 4.

Associated with the pin 5 and'no mally holding it immovable in the upper end f the slot 16, is a latch member Shaving a phlling the means for main-- aid braces 4 are pivot-f member 9 connected to the end thereof. Near the upper end of the latch member 8 1t s pivotally connected, as at 10, between supports 11. The said upper end of the latch member 8. is beveled as at 12. Engaging with the beveled end of the latch member 8, 1s a flat spring 13, which is secured as at 14, to the scoop-carrying member 1.

The function of the spring 13 is to maintain the latch member '8 closed until the same is reeased by pulling upon the flexible mem- The function of the pin 5, when released by latch member 8, is to slide down slot 16, carrying braces 4 and dropping the open end of the scoop 3, dumping its load. 2

A pulling member 21 is pivotally connected with the scoop-carrying member 1, at

19, by rods 19 and sheave 18. The said sheave, 18 is also pivotally connected with pulling member 21 may be operated by any suitable means. Said boom 15 is adapted to be pivotally connected with the machine, as at 26. A pulling member 23 is connected with the scoop 3, by a bail 27, and passes between the sides of the boom 15, over sheaves 24 and 25 to any suitable machinery.

The function of the pulling member 21 is to retract the upper end of the scoop-carrying member. 1, causing the scoop 3 to reach out, or to lift the boom, or both at the will of the operator and the function of the pulling member 23 is to pull the scoop 3 through 1 the material or to prevent pulling member 21 from extending the scoop3 farther than is desired by the operator.

It will be observed that by holding pulling member 23 immovable and operating pulling member 21 that the boom 15, the scoop 3 and scoop-carryin member will all be elevated on the axis of t e pivot at 26.

In the operation, assuming the device to be in the position shown in Fi 1, .the pulling member 21 is gradually re eased lowering the boom 15 until the scoop 3 is in contact with the material to be removed, then pulling member 23 is operated to move the scoop through the material in the direction of the sheave 24, pulling member21 being operated fast enough to lower or raise the boomto gage the depth of the out. After the scoop. 3 has been moved to a position 1 near the sheave 24, and kept there bypulling member 23, pulling member 21 is then operated and elevates the boom 15, with the scoop 3, on the pivot 26. It is then adjusted laterally over the dump and the scoop 1s unloaded by operating pulling member 9. After the scoop has again been placed ,over the cut pulling member 23 is released causing the scoop 3 to reach out for another stroke.

The point of the scoop 3 coming in contact with the material will causefthe pin 5, to slide to the top of the slot 16, and engage with the latchmember 8.

What I claim is v 1. An excavating machine including a boom, a scoop carryingmember pivotally connected with the boom intermediate the ends of said carrying member; with the greater portion of the length of the carrying member depending from the boom, a scoop attached to the scoop carrying member, a pulling member connected with the scoop for shifting it into the material operated upon, and means operatively pivotally attached to and connecting together the upper adjacent portions of said boom and carry-.

mg member adapted for simultaneously shifting said boom and scoop carrying member.

2. In an excavating machine a pivoted boom, a scoop-carrying member pivotally means carried by the boom and connecting the "pulling member therewith, and with said scoop-carrying member.
